Cole is now starring on-loan at Lille this season.
"I spoke to him about coming here to QPR before he went to Lille. I've known him since I was about 12 years old," Bothroyd told the Sunday Telegraph.
"We used to play for Islington district together. He was a bit different then, all about juggling and flicking balls over people's heads. He would run round the whole team and then square on the line for me to tap in."
